Which client demonstrates an expected outcome after a carotid endarterectomy?

A client who maintains a blood pressure greater than 90/60 mm Hg after a carotid endarterectomy demonstrates an expected outcome of the procedure. This surgical intervention aims to reduce the risk of stroke and improve blood flow by removing plaque from the carotid arteries. Following the surgery, it is crucial for the client to maintain stable hemodynamics, which includes having an adequate blood pressure. A blood pressure reading above 90/60 mm Hg indicates that the client has sufficient perfusion to vital organs, which is a positive sign in the postoperative period.

The other options represent potential complications or concerns following the surgery. A high heart rate can indicate pain, anxiety, or inadequate oxygenation, rather than a desirable outcome. The development of neurological changes, such as confusion or weakness, could suggest a complication such as a stroke or transient ischemic attack, which would be worrisome. Lightheadedness could indicate hypotension or inadequate cerebral perfusion, which are not expected outcomes after the procedure. Maintaining stable blood pressure is a key indicator of recovery and an expected outcome following a carotid endarterectomy.
